The magnetic field in a plane electromagnetic wave is given byB_(y)=2xx10^(-7)sin (0.5xx10^(3)x + 1.5 xx 10^(11) t)T. Write an expression for the electric field. |

Answer» Solution :`E_(o) =B_(o)c =2xx10^(-7) TXX 3XX10^(8) m//s =6XX10^(1) V//m` The electric field component is perpendicular to the direction of propagation and the direction of MAGNETIC field. Therefore, the electric field component along the z-axis is obtained as `E_(z) =60 sin (0.5 xx10^(3) x +1.5 xx10^(11) t) V//m` |
